Smaller battery banks relied on heavily for inverter duty could really profit from AGM rather than dlooded batteries. The upgrade performance wise, is impressive.
Yep!, that has been my experience.
This past winter while in Quartzsite, AZ, purchased a Magnum 1012 1000W/50A inverter charger. I wanted to shake it down.
I ran a MW and a coffee maker for a total of 30min from a 53lb 79AH AGM with a 1000W PSW inverter/charger. At 9.54 Volts, the inverter invoked its LVD to protect itself from the rise in Amps to maintain the Wattage draw.
The coffee maker was a small Mr. Coffee that uses 600W and the MW is an inverter Panasonic model that uses constant/steady 675W on power setting 4. That represents about a 700W draw or about 70A from the AGM.
This was in the AM and after the AGM had run two(2) Dometic CF-35 12V fridges overnight.
This AGM had just started its 6th year of use.
How sweet it was to recharge the 79AH battery with a 50A multistage charger! That is a puny 62% of battery AH. That is where temperature compensated chargers earn their keep.
Are there any accounts of working a comparable size flooded battery like this?
